Download ROM - * temporary removed for small investigation.

Instructions:

It is recommended to start off with a stock rom and kernel to stay away from possible bootloops

As far as I know, the guy used a few people's "work" without asking for permission, etc and as usual everyone complained there which lead to forum thread being closed aswell as download link being removed.

I will review this ROM in a few minutes to see if it uses any paid apps or anything else suspicious, will remove then, re-sign zip and post a download link.

As for other people's "stolen work" from xda-developers as they didn't create those apps from scratch, they themselves have also modded/themed the system apps which come from Android which is open-source, blah blah blah.

tl;dr: Once this ROM is warez free, a download link will be shared along with a video.

Ok so instead of wasting my time flashing this just to test and ruining my sd-ext partition, could you please tell me the list of apps that come installed with this rom?Is for example AnTuTu CPU Master Pro installed?

As for your question sorry I cannot answer as I still haven't tried the rom.

Flash a stock rom with Odin. You can't go to Recovery mode but Download mode is accessible so just take off the battery, put it back in, boot into Download mode (hold volume down + Power button + home button) and flash a stock rom with Odin. It will be as good as new.

please dont try this guysjust for your safetybetter stick to your gingerbread device or get a new jellybean onethe developers are never gonna take responsibilty even if you do all the steps correctlyjust fool people in the hunt of a richer experience
